METHOD orronMINGcM/IENT BLOCKS.

Application `filed .Tune 2,

rIhis invention relates to an Aimproved type ofcement block ,havingcolored inlaid sections adaptedrto be produced in the forming of a block by,` `an improved forming method, adapted to be accomplished by means of an adjustable die and aA pressure V producing mechanism.

It is an object .of this invention to provide an improvedmethod whereby cement blocks 4maybe readily formed with colored sections arranged to produce a fanciful configuration inthe face ofthe block.

It'isalso an object of this invention to pro-y videa `sectional die fmechanism havinga pressure producing -mechanism co-acting therewith topermit colored inlaid sections of a ,cement block to ,be formed prior to `the form- 'ingof the main body vof theb'locl.

1tis a further object of .this invention to provide ,an improved typekotl yinlaid cement block by lirst formingfcolored,cement inlay sections spaced from one another inthe form of a selected design, after lwhichthe spaces between the lcolored yinlay sections areiiled r witha dry cementafter which acementinixture is deposited uponthe inlaysections and .the dry cement,l and ispressed thereon to sequeeze the moisturetherefrom, causing the excess moisture to be absorbed by the dr 1 cement, thereby. `forming a lcompleted inlaid .'block.

It isan-important object of this invention to provide an ,improved `type ofisectional die with which a V pressure V,producing ,mechanism isadapted to co-acttoV permitceu'ient inlayV Vblocks to beA rapidly and conveniently Aproduced by an improved method, insuring the production of cement blocks having inlaid Vportions arranged to produce any desirs/d fanciful configuration inthe top surfaceof a block.

Other and further important objects of this invention willbe apparent from the disclosures inthe specification and the accon panyingdrawings.

As shownon the drawings:

The reference numeral 1 indicates atable or `support provided with a hollow topsection 2 Vwithin wliich bearing sleeves y3 are mounted for rotatably supporting a shaft. l

an improved in.-

tlie support land is 4adapted to be operated manually by means of a crank or by any' suit?. able source of power. Secured on the operab ing shaft 4t is a spiral gear which meshes with Vwhich projects outw'iardly from one side of a spiral gear which is internally'threaded and engaged on ahollfow4 screw '6 projecting through the top ofthe support l.` The hollow screw 6 is rotatably engagedon a`pin or verticalstub shaft 7 proiecting'axialfly through ftheI screw 6 and having the' upperl end v'thereof `lreyed orotherwise secured in arecessed shank or sleeve @integrally formed centrally upon the bottom f a die supporting disc or plate9 yhaving a plurality of,countersunlrpassages therein, through which `rietain'ing `screws lO are engaged with the upper projectingends of said screwsv threaded into suitableape'rtures provided in a pluralityof adjustable blocks 11 and 12 of any desired orselectcd shape adapted to slidably lit upwardly into complin'ientally .shaped passages or recesses provided in a die plate 13 resting upon avtable plate 1 4 secured upon the top ofthe support 1 and having a middle opening 1 5 therein through which the die supportingplate'z) jis adapted to Vmove to vary the .position of the die blocks 11 and .12 with respectvto the die plate 13. h lountedupon the'die table plate 14 isa vertically 'adjustable or slidable upper die plate 16 havinga guide 'sleeve or collar 17 integrally formed ontlie upper surface' thereof. vThe lower middle portion of the upper die plate 1Gis pro'videdwith arece's's orgr'oove 18 adapted .to scat over the main'die plate 13 when thefupper die plate 16 is in its 'lowered position resting upon the upper surface of thelowerjtable plat-elli. The-uppery dielplate 1 6 is provided with a plurality of openings :to lpermitthe slameto slide'upwardly'onf a Y are to be plurality of guide posts 19, the lower ends of whichare secured in the table plate 14.

Secured to the upper end of the guide or collar 17 are a plurality of bolts 2() which project through suitable openings or passages provided in a pressure plunger 21 having a plurality of guide sleeves 22 formed thereon and slidably engaged on the guide posts 19. Secured to the bottom central portion of the pressure plunger 21 by bolts 23 or other suitable means, is a pressure or plunger block 24 which is adapted to slide downwardly into telescoping engagement with the guide sleeve 17. Formed centrally upon the top of the pressure plunger 21 `is a-boss or shank 25 in which is secured the lower end ofan operating screw 26, adjustably projecting upwardly through a suitable opening inthe top member 27 of a yoke or frame28 mounted upon the support `1. Rotatably engaged on the plunger screw 26 below the top frame member 27 ,v is an internally threaded bevelled gear 29 supported above a bracket 30 secured to the top frame member 27. The bevelled gear 29 is in mesh with a bevelled driving gear 31 supported on an operating shaft 32 journalled in the top frame member 27 and operable by means of a hand wheel 33 or any other suitable driving means. Figures 4 and 5 illustrate an inlaid cement block comprising a body section 34, the upper portion of which is formed of a plurality of inlaid colored cement sections 35 and 36 arranged or grouped to provide a fanciful configuration with said inlaid sections 35 and 36 separated with a cement filling designated as a whole by the reference numeral 37 formed from a dry cement filling and ,moistened during the formation of the block from water squeezed or Vpressed from theV body section 34 of the block lduring the formation thereof. i Y

The improved method whereby inlaid cement blocks are adapted to be formed is adapted-to be accomplished by means of the described machine in which the hand wheel which is adapted tobe operated to raise the plunger plate 21 and the pressure block 24 upwardly tofdisengage said pressure block 24 from its engagement with the guide sleeve 17. lith the continued raising of the plunger plate 21, said plate is moved into engagementwith the heads of the bolts 2O therebyV causing the upper die plate 16 to be raised' out of engagement with the die mechanisms. The lower shaft 4 may now be rotated to cause rotation of the lower adjusting screw 6 to lower the die supporting plate 9 and the adjustable die blocks 11 `and 12 mounted Vthereon an amount equal to theV desired depth of the inlay sections 35 and 36 which formed. After adjusting the die blocks 11 and 12 with respect to the main dic plate 13, a cement mixture colored to any desired shade is poured into `the recesses or pockets formed in the main die late 13 due to the result of the lowerin o the adjustable die blocks 11 and 12. AA ter the adj usted die has been filled with a colored cement, the

Vdeposited cement is leveled off flush with the upper face ofthe main die block 13, thereby forming the colored cement inlay sections 35 and 36. `The hand'wheel 33 is now operated in the reverse direction to cause a lowering of the plunger plate 21, permitting the upper die plate 16 to be lowered into a positionin which the notched portion or groove 18 seats j over the vedge ofthe main die plate 13 with said upper die block or plate 16 resting upon the table plate 14, as clearly illustrated in Figure 2. This position of the upper die plate16 and its guide sleeve 17 is reached before the pressure block 24 enters thedie sleeve 17 At this stage inthe operation, the lower shaft 4 is again rot-ated to cause the adjustable die supporting plate 9 to be raised or projected upwardly through the main die plate 13, thereby causing thel adjustabledie blocks 11 andV 12 to push the formedcolored inlay sections 35 and V36 out of said main die plate 13 within the openingprovided within the die sleeve 17. In the raised position of the colored inlay sections, spaces are provided between the samewhicharel now filled with a dry cement which is leveled off flush 4with the upper faces of said inlay sections 35 and 36. A wet cement mixture is next deposited in the guide sleeve or form 17 upon the colored inlay sections and said dry cement fillin The amount of wet cement mixture deposited in the block form 17 depends upon how thick a block is to be formed.

After the wet cement mixture has been desqueezed from. the wet cement mixture is ab sorbedby the dry cement filling between the colored inlaysections `to form a Vcement filling 37 which serves to bind orV unite the colored inlay sections with the main body porj tion 34 to form a cement block having colored sections inlaid in the upper portion thereof and separated by the cement filling 37 thereby giving the upper face of the formed block an artistic appearance with said sections liu forming a set design as illustrated in Figure 4 of the drawings. After a block has been j formed as described, the plunger plate 21 and pressure block 24 are raised out of engagement with the form 17, afterwhich said rising plunger plate 21 engages the heads of the bolts 20 to raise the form 17 and uplper die plate 16 out of engagement with the formed block which remains upon the main die plate 13. With the pressure parts'elevated above besarme the main die mechanisms, the formed block may be removed olf of the main die plate 18 and placed in .a convenient position to permit the cement to set and harden.

It will thus be seen that an inlaid cement blocl; is adapted to be readily formed with the inlay sections formed of colored cement. The inlay sections may be of various shapes and of different colors as preferred. The colored sections are formed first, after which the sections are raisedabove the level of the main die plate and the spaces between said sections are filled with dry'cement, which is later covered by a wet cement mixture poured into form 17 and compressed, permitting the moisture squeezed therefrom to be absorbed by the dry cement to form a solid inlaid block.

I am aware that many changes may be made, and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent necessitated y the prior art.

I claim as my invention:

l. A method of producing an inlaid cement block consisting of first forming a plurality of spaced colored cement inlay sections, then filling the spaces between said colored inlay sections with dry cement, and.y

covering the colored inlay sections. and the dry cement with a wet cement mixture which is compressed to force the water therefrom,

permitting said water to saturate the dry eement to form a solid cement block.

2. The method of producing an inlaid cement block consisting of forming spaced colored inlay sections, then filling the spaces within said sections with a dry cement, leveling said cement even with the upper faces of said sections, then engaging a form around said colored inlay sections and depositing a wet cement mixture in said form above said inlay sections, then compressing the wet cement filling causing the water pressed therefrom to be absorbed by said dry cement, and then removing the pressure. producing means and the form from the compressed inlaid block and removing said block from the supporting dies.

3. The method of producing an inlaid cement block consisting of forming colored cement sections, separating` said sections with a dry cement, depositing a wet cement mixture over the dry cement and said colored inlay sections, and then compressing the said colored inlay sections, the dry cement and granted hereon, otherwise than said wet cement mixture to form a solid cement block having the colored inlay sections embedded in one face thereof.

2l. The method of producing` an inlay block consisting of forming a; plurality of colored cement sections arranged in a fanciful configuration, filling the space betweenV said sections with a dry powder and covering the powder and said coloredv sections with a moistened mixture, and applying pressure to the entire mass to cause moisture from the moistened mixture -to be pressed therefrom and absorbed by the dry power to form, a solid block with vthe moistened powder, uniting said'inlay sections with the-compressed mixture to forman inlaid block.

5. The method of producing an inlaid block consisting ofl forming a plurality of spaced colored inlay sections in a die, then elevating said formed inlay sections to provide spaces therebetween which are filled with a dry powder, and then vcovered by a wet mixture, to which pressure is applied to squeeze the moisture therefrom to permit said moisture to be absorbed by the powder to convert the same into a binding' mixture for uniting the formed colored inlay sections with said compressed mixture to form an inlaid block.

6. The method of forming a fancy inlaid cement block consisting of forming a plurality of colored inlay sections arranged in a fanciful configuration, depositing dry matef rial therebetween and then covering the same with a wet mixture which is compressed to cause the moisture therein to be absorbed by the dry material to cause the same to act as a filling andv binding between the colored inlay sections and said compressed mixture to form a solid block.

7. The method of producing` an inlaid block consisting of forming inlay sections of a moistened colored mixture, separating said sections by a dry powder, and then covering said inlay sections and the powder by a wet.-

mixture and compressing the entire mass to cause the moisture squeezed from thel inlay sections and said wet mixture to be absorbed by the dry powder to form the same into a binding material uniting the sections with the compressed material yto produce a block having a fanciful colored design embedded therein.
